Thanks to a collaboration across city agencies, engineers, a “carrier hotel” and others, Amazon’s newest building is heated by recycling excess energy from a neighboring data center. Compared to traditional heating methods, this approach is nearly four times more efficient—and completely imperceptible to employees and visitors.

Our newest, largest wind farm – Amazon Wind Farm Texas – is up and running, adding more than 1,000,000 MWh of clean energy to the grid each year. To date, we’ve launched 18 wind and solar projects across the U.S., with more than 35 additional projects to come.

The Amazon smile box now comes with even more sunshine. Today we announced that we’ve begun hosting solar installations on the rooftops of our fulfillment and sortation centers with a goal of installing at least 50 solar systems by 2020.

On the heels of our recent Texas Wind Farm announcement (our largest renewable energy project to date) we were honored to welcome Al Gore to Amazon last Friday. Al Gore is former Vice President of the United States and current Chairman of Generation Investment Management.

Today we announced our largest renewable energy project to date, Amazon Wind Farm Texas. It's the newest renewable energy project in our long-term sustainability efforts across Amazon, which include wind and solar farms, green rooftops, and the District Energy Project—a system we built in Seattle to heat our office buildings with recycled energy.

At Amazon we are constantly looking for ways to further reduce our environmental impact. This spans our company – including things like our wind and solar farms, innovative building design, Frustration-Free Packaging, support of the Environmental Protection Agency's Clean Power Plan and initiatives like the “I Want to Be Recycled” public service campaign. With our growth and current scale, we can put our inventive culture to work on further moving the needle on sustainability issues. Here's a bit more about a few of those things we're already doing.
